The 2" height of the K3's tilt stand is a compromise: lower than the K2, higher than some other rigs. We arrived at this height after a lot of experimentation, and would rather not change it. All of our tilt stands are custom-designed, so we incur significant tooling costs. The K2 tilt stands (1.5 and 2.5") will not fit on the K3. 73, Wayne N6KR
